QuickCheck is a library for random testing of program properties.
The programmer provides a specification of the program, in the form of
properties which functions should satisfy, and QuickCheck then tests that the
properties hold in a large number of randomly generated cases.
Specifications are expressed in Haskell, using combinators provided by
QuickCheck. QuickCheck provides combinators to define properties, observe the
distribution of test data, and define test data generators.
